To test I configured the inbound dialplan to play two wav files before transferring the call...<br>
<br>1) 8kz wav from wikipedia <a href="http://www.nch.com.au/acm/8kulaw.wav" target="_blank">http://www.nch.com.au/acm/8kulaw.wav</a><br>2) /usr/local/freeswitch/sounds/en/us/callie/ivr/48000/ivr-you_are_number_one.wav<br>
<br></div>Both play fine, as soon as the call is transferred to voicemail (via extension 1000 that is not registered at the time) the quality drops and I start loosing speech. I've tried preferring the PCMU codec within vars but I seem to have a lot of
"TRANSCODING_NECESSARY" messages, they are not isolated to the
voicemail steps however.<br><br></div>Has anyone got an idea where I can start to look? Any help would be much appreciated.<br><div><div><div><div><div><div><div><div><div><div><div><div><div><div><div>
